Compatibility

Kinesis Aithein Disc is a Kinesis road frame. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions

What fits Kinesis Aithein Disc?

On this page we list brake calipers this frame mounts, bottom brackets for this frame shell, seatposts for this seat tube, forks with a matching steerer and wheel size. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.

Can I mix Kinesis Aithein Disc with MTB components?

Kinesis Aithein Disc is recorded as a road component. Some standards do carry across (cassette spacing at a given speed count, for instance), but cable pull ratio and chainline frequently differ between road and MTB groups, so check the specific pairing rather than assuming it carries over.
